First of all automobiles and combustion engines give off carbon monoxide, not dioxide. and carbon emissions are overall to blame.
to sum it up people exhale carbon dioxide. plants, oceans, etc take in and absorb it back into the earth. I won't get into too much detail, but the oceans deposit it into the ocean floor and is recycled, so to speak, through plate techtonics. plants store it die, decompose, turn into oil, coal, etc. the people/animals, plants, oceans etc. balance eachother out naturally. The problem comes in when people harvest these carbons in fossil fuels such as oil and coal, burn them and put the carbon back into the atmosphere. naturally this increases the amount of carbon in the atmosphere exponentially since it sets off the natural balance. the results of this are global warming, pollution, etc.
hopefully this simplifies how basic this science is. we are basically harvesting carbon unnaturally and dumping it into the atmosphere throwing things out of whack.
